Health Hazards Acute and Chronic:EYES: IRRITATION. INHALATION: FUMES OR
DUST FROM CASTING MAY CAUSE PIGMENTATION (SIDEROSIS).
Explanation of Carcinogenicity:HEXAVALENT CHROMIUM & NICKEL ARE
SUSPECTED TOBE AN A1 CARCINOGEN BY ACGIH.
Effects of Overexposure:EYES: IRRITATION. IHALATION: FUMES OR DUST FROM
CASTING MAY CAUSE PIGMENTATION OF THE LUNG (SIDEROSIS).

First Aid:INHALATION: REMOVE TO FRESH AIR. EYES: OBTAIN MEDICAL

CASTING THAT ARE UNCLEANED OR HAVE EMBEDDED SAND WILL GENERATE DUST
(FREE SILICA).
Other Precautions:FLAME CUTTING, ARC GOUGING, OR WELDING ON THE CASTING
